This page shows you stages in the construction of my latest telescope, a 32-inch diameter main mirror, with 5 corrector lenses. It is a 5200 mm focal length f6.5 when used as a camera.
This telescope is completely homemade, including optics which were ground and polished by me. Every part (680 of them) are either recycled scrap, new aluminum, or carbon fiber parts, manufactured at home on my lathe or milling machine. The dome was also completely homemade.
